84 Vulnerabilities Discovered in 4G/5G Core Networks, Including Session Hijacking Flaw
What Happened — Researchers from Nanyang Technological University identified 84 distinct security flaws across 4G and 5G core network implementations. The vulnerabilities span denial‑of‑service (DoS) vectors and a session‑hijacking flaw that could let an attacker take over a user’s network session.
Why It Matters for Compliance & Audit Readiness
- The flaws illustrate a classic control‑gap scenario that SOC 2 continuous‑compliance programs are built to detect, remediate, and evidence.
- Mapping these technical findings to SOC 2 control families (e.g., CC6.1 System Operations, CC7.1 Change Management) provides audit‑ready proof that network‑level risks are being managed.
- Verisq’s Control Mapping capability can automatically align discovered vulnerabilities with the relevant SOC 2 controls and generate continuous evidence for auditors.
Who Is Affected – Telecommunications operators, mobile‑network service providers, and any enterprise that relies on 4G/5G core infrastructure (e.g., MVNOs, IoT platform providers).
Recommended Actions
- Catalog the 84 flaws against your SOC 2 control matrix (focus on System Operations and Change Management).
- Deploy continuous vulnerability scanning of 4G/5G core components and integrate findings into your evidence‑collection pipeline.
- Prioritize patching or mitigation for the session‑hijacking vulnerability; document remediation steps for audit review.

Technical Notes
- Attack vectors: exploitation of protocol‑level weaknesses in the core network (Vulnerability Exploit).
- Potential impact: DoS of mobile services, unauthorized session takeover, exposure of subscriber data.
- No specific CVE IDs were disclosed in the study; the researchers plan to coordinate with vendors for individual advisories.
